Ely Vaughn is one of the strongest pillars of a society that needs him for each and every funeral, as he is their much revered mortician. Smithville, the tiny city in Texas, has Elle as one of its highly respected and indispensible members, who was once well-known for his stunts as the high school team’s quarterback. Ely was humble and friendly with the whole town till the tragic death of his beloved wife, who was his only companion in this world, two years ago. Ely has not maintained talking terms with anyone in the town, and somehow, had managed to hibernate since then. His neighbors had seen very little of him since then and the young boys in town believe that there exists a supernatural angle to this story. They assume that some paranormal activity must be on inside his mansion, which is also the funeral house.

As we watch Beneath the Darkness online, we find four young kids from the town – Travis, Brian, Danny and Abby trying to spy into the mansion, to have a look at all that was happening inside. To their surprise, peeping through the curtains of the bedroom, they find the supposed-to be-sad Ely dancing with a mysterious lady. All the four kids turn high on curiosity and wait for Ely to leave the premises. Once inside the mansion, instead of the dancing woman, they stumble upon a deadly secret that had been hidden since ages, revealing the sadistic nature of the mortician. Now Ely will try one last time to prevent truth from leaking out in public by slaying down kids, if it needs that.
